Flason Posted January 4, 2007 Share Posted January 4, 2007 Came across a pair of Chorus II's that have 1 torn passive radiator. Is it better to re-cone, replace, or maybe epoxy? I usually have the fronts set to large. Anybody? Quote Link to comment Share on other sites More sharing options...
Guest " " Posted January 4, 2007 Share Posted January 4, 2007 The radiators are relatively inexpensive.....best bet is to replace. Any repair to the radiator, adds weight to the cone. In a radiator, additional grams of weight is used to tune the range the radiator operates across. Tipically the radiator is tuned by adding weight to operate slightly below the woofers resonant frequency. The radiator overlaps this above and below that point at 18db per octave. Adding additional wieght via a repair, will move the center point of the radiators range furthur than the resonant frequency of the woofer. The furthur these points get, the less impact the radiator will have on the speakers performance. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted January 4, 2007 Share Posted January 4, 2007 rubber cement, clear fingernail polish, or weldbond adhere well, hold up to vibration and hardly add any weight. If the tear is beyond 3/4" or so, time to replace the unit- call Klipsch. Quote Link to comment Share on other sites More sharing options...
JDJohnson Posted January 4, 2007 Share Posted January 4, 2007 If it's a small tare. Cut a piece of single ply toilet paper just a little bigger than the tare to cover it like a bandage. Place just regular Elmer's white glue on the front and back side of the toilet paper patch until it is soaked. Apply it over the tare and press it flat on to the speaker. I use tweezers to hold on to the patch to apply it to the tare position. Take your time and be gentle. Apply to the back side of the speaker, so the patch does not show. Tissue paper does not work, because it tares too easily and paper towel is too thick. Allow glue to dry fully or use blow dryer if you want to dry it fast. This patch will dry like a hard piece of paper. I've done this more than once and it works great! Just another great use for toilet paper.

HarryO Posted January 4, 2007 Share Posted January 4, 2007 If those are the ones from Ohio that were on Ebay recently it should be replaced. They can be repaired by patching from the rear and using surround adhesive or a suitable substitute. HarryO Quote Link to comment Share on other sites More sharing options...
Flason Posted January 4, 2007 Author Share Posted January 4, 2007 Thanks for the replies. The tear is over an inch long. Will give Klipsch a call in the morning to get a price. Hopefully they will still have some in stock. If not, is it OK to get a passive reconed? Quote Link to comment Share on other sites More sharing options...
